Thermo‐Hydro‐Mechanical Behavior of Saturated Porous Media Under Non‐Isothermal Flow With Fine Particle Migration

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Clogging of reservoir formations, known as permeability damage, and wellbore clogging due to mobilization and straining of in situ fine particles are critical challenges in enhanced geothermal systems. This study presents a novel fully coupled thermo‐poro‐elastic model to predict the thermo‐hydro‐mechanical (THM) response of saturated porous ...

Kinematic Limit Analysis of Roof Stability for Elliptical Tunnels in Rock Masses

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Noncircular cross‐sections are commonly encountered in engineering practice; however, primary attempts to analyze roof stability have focused on circular and rectangular configurations. This study investigates the roof stability of elliptical tunnels with varying aspect ratios, employing two semi‐analytical approaches: piecewise linear and ...

Comparative Insights Into the Structural, Electronic, Elastic, Vibrational, and Optical Properties of Rare‐Earth Palladium Borides RBPd3 (R = Lu, Yb)

Nano Select, EarlyView.
This study focuses on the ground‐state properties of two rare earth palladium borides, LuBPd3 and YbBPd3. The WIEN2k package is used to investigate the properties. The compounds’ exceptional thermal and optoelectronic properties make them suitable for high‐temperature applications, UV absorbers, and infrared (IR) shielding materials.

Multi‐scale geophysical imaging of neotectonic fault activity in the northern Upper Rhine Graben, Germany

Near Surface Geophysics, EarlyView.
Abstract A comprehensive multi‐method geophysical strategy is used to investigate two faults in the Northern Upper Rhine Graben. Combining industrial 3D seismic data with our own 2D P‐ and S‐wave seismic, electrical resistivity tomography (ERT) and ground‐penetrating radar (GPR), we created comprehensive subsurface images of the faults. 3D seismic data

Using Vp$V_p$ and Vs$V_s$ to characterize the spatial extent of shear strengthening under a longleaf pine

Near Surface Geophysics, EarlyView.
Abstract Tree roots modify the elastic and mechanical properties of soil. High‐resolution seismic refraction surveys offer a novel, noninvasive approach to characterize how roots impact the elastic properties of soil beneath trees. This study presents two perpendicular profiles of P‐wave (Vp$V_p$) and transversely polarized S‐wave (Vs$V_s$) velocities ...
